In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
My 1 year old burnham boiler has (2) 2" pipes coming off for the supply connections. One of these is capped off, the other is connected. The installation instructions indicate that connecting the second connection is optional for this size heater. From reading "The Lost Art of Steam Heating" it indicates that connecting the second one is very desirable to create dry steam. Should I connect it? Picture attached. (capped off tap is behind the red shut off switch...)
